Changes in directory llvm/lib/System/Unix:
Process.inc updated: 1.16 -> 1.17
---
Log message:
On Mac OS/X, make Process::PreventCoreFiles disable crash reporter for
the process in addition to disabling core file emission. This speeds up
bugpoint on default-configured macs by several orders of magnitude.
